Description

Technical Field

[0001] The invention belongs to the technical field of ore processing, in particular to a mine ore sampling device. Background Art

[0002] During mine exploration, mining, and ore quality testing, the accuracy and efficiency of ore sampling equipment directly impact the reliability of subsequent analysis and decision-making. Currently, common ore sampling equipment typically uses an auger conveyor rod (spiral drill rod) as the core sampling mechanism, which extracts ore debris or core samples from the borehole to the surface or into a storage container through rotational propulsion.

[0003] For example, the utility model with publication number CN113375961A discloses a sampling device with ore crushing function for geological exploration, including a cart, universal wheels are fixedly connected to the front and rear sides of the right side of the bottom of the cart, a handle is fixedly connected to the left side of the cart near the bottom, a box is fixedly connected to the top of the cart, a first circular hole is opened near the center of the bottom of the box inner cavity, a second circular hole is opened on the top of the cart, and the first circular hole and the second circular hole correspond to each other, a sampling mechanism is provided near the top of the box inner cavity, and a plurality of second springs are fixedly connected to the inner cavity of the box near the left side, a telescopic moving rod is provided in the inner cavity of the second spring, and the top ends of the plurality of second springs are fixedly connected to a U-shaped frame, and a discharge mechanism is provided at the bottom of the inner cavity of the U-shaped frame. The present invention has a reasonable structural design and can crush and sample ore, making it convenient for staff to study and mine it.

[0004] Most existing sampling devices utilize a drill bit, an auger conveyor, and a sample storage container for sampling. While this can meet basic requirements for single-point sampling, actual mining operations often require multi-point sampling of ore at different depths or locations to more comprehensively analyze ore distribution, grade variations, or differences in mineral composition. Existing sampling equipment is limited to single-sample storage, making continuous stratified sampling impossible. Typically, only a single sample storage container can store ore samples from a single location at a time. Collecting multiple samples requires frequent container replacement or cleaning, resulting in low efficiency and the potential for sample confusion or contamination due to improper operation. Furthermore, during deephole drilling or stratified ore exploration, ore composition can vary significantly at different depths. Due to the lack of multi-sample storage capabilities, conventional equipment struggles to collect and independently store samples by depth within the same borehole, compromising the accuracy of subsequent analysis. When collecting multiple samples, operators must repeatedly disassemble the sample storage container or manually aliquot the samples, increasing labor intensity and potentially distorting data due to human factors (such as incorrect sample labeling and cross-contamination).

[0005] Therefore, a mine ore sampling device is proposed to solve the problems raised in the background technology. Summary of the Invention

[0011] Preferably, the disassembly assembly is used to quickly disassemble and separate the sampling cylinder and the sealing sleeve; The disassembly and assembly assembly includes two plugging plates fixedly arranged on both sides of the top of the circular plate, two arc grooves opened on the top of the sealing sleeve and a limit plate rotatably arranged on the top of the plugging plate. The plugging plate and the limit plate are the same size and shape and both are slidably inserted in the arc groove, and the limit plate abuts against the top of the arc groove.

[0012] Preferably, the adjustment assembly includes a rotating frame rotatably arranged on the driving rod, a rotating disk fixedly arranged on the top of the protective sleeve, a driving disk rotatably clamped inside the rotating disk, a connecting column fixedly arranged at the top center of the driving disk, a protrusion fixedly installed on one side of the connecting column, a rotating rod fixedly arranged at the top center of the connecting column and rotatably connected to the top of the moving seat, and an adjustment motor fixedly arranged on the top of the moving seat for driving the rotating rod to rotate.

[0016] Preferably, the crushing mechanism and the partition sampling mechanism are both located at the top of the slot, and a collection box is placed on one side of the top of the movable seat.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates the zoning sampling of ore by arranging the coordination of structures such as the sampling barrel, the sealing sleeve, the driving assembly and the adjusting assembly. After being moved to the sampling location by the coordination of the universal wheel and the pusher, the ore is crushed by the motor of the crushing mechanism to drive the drill bit and the crushing drill, which is convenient for subsequent sampling. During sampling, the sampling barrel is controlled to move downward by the electric cylinder, and the sampling height is adjusted with the help of the adjusting block and the electric push rod. At the same time, the driving assembly adjusts the relative position of the sealing sleeve and the sampling barrel so that the through groove and the sampling groove coincide to achieve sampling, and prevent sample overflow after closing. The adjusting assembly can adjust the positions of multiple sampling barrels to achieve the zoning sampling function, which solves the problem that the existing ore sampling equipment has a single sample storage limitation during the sampling process and cannot achieve continuous stratified sampling. When sampling samples at different locations or depths, it is necessary to manually replace the sample storage container frequently, resulting in low operating efficiency and the problem that improper operation may cause sample confusion or contamination.

[0018] The present invention facilitates the adjustment of the states of the sampling tube and the sealing sleeve by arranging the coordination of structures such as the first gear, the second gear and the disassembly and assembly assembly. The driving rod is driven to rotate by the crushing motor, which drives the second gear to engage with the first gear for transmission, so that the electric cylinder and the sealing sleeve rotate synchronously, thereby adjusting the opening and closing state of the sampling slot, which is convenient for sampling and transporting samples. The disassembly and assembly assembly adopts a rotatable limit plate and plug plate structure. By manually rotating the limit plate to align or be perpendicular to the plug plate, the sampling tube and the sealing sleeve can be quickly disassembled and assembled, which is convenient for cleaning and replacement. The limit plate and the plug plate are made of elastic rubber material to ensure stable installation and good sealing to avoid falling off or leakage.

[0019] The present invention facilitates the adjustment of the positions of multiple sampling tubes by arranging a rotating frame, a rotating disk, and a drive disk. By adjusting the motor to drive the rotating rod, which drives the protrusion and drive disk to rotate, the rotating frame rotates intermittently, thereby adjusting the positions of multiple sampling tubes and achieving zoned sampling. During sampling, the electric push rod adjusts the height of the sampling tube to accommodate ore of varying depths. After sampling, the drive assembly closes the sampling slot to seal the sample. The adjustment assembly rotates the sampled sampling tube to the top of the collection box to release the sample, and simultaneously moves the unsampled sampling tube to the slot position for the next round of sampling, achieving cyclic sampling and automatic collection functions.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 9 As shown, the present invention provides a mining ore sampling device, comprising a mobile base 1, universal wheels 11 fixedly arranged at the four corners of the bottom of the mobile base 1, a push handle 12 fixedly installed on the side wall of the mobile base 1, and a notch 13 opened at the bottom of the mobile base 1. The mobile base 1 is U-shaped; Crushing mechanism 2, which is located on the top of the moving seat 1 and is used to crush the ore to be sampled; The partition sampling mechanism 3 is arranged around the crushing mechanism 2 and is used to sample soil at different positions and heights; The partition sampling mechanism 3 includes a plurality of sampling cylinders 31, a sealing sleeve 32 rotatably arranged inside the sampling cylinder 31, an adjustment block 33 sleeved inside the sampling cylinder 31, an electric push rod 331 fixedly mounted on the top of the adjustment block 33 and fixedly connected to the top of the sealing sleeve 32, an electric cylinder 34 fixedly mounted on the top of the sealing sleeve 32, a driving assembly 35 arranged on the top of the electric cylinder 34, a disassembly assembly 36 located on the sampling cylinder 31, and an adjustment assembly 37 arranged on the top of the movable base 1 for adjusting the positions of the plurality of sampling cylinders 31; The crushing mechanism 2 includes a drill bit 21, a driving rod 22 fixedly mounted on the top of the drill bit 21, a plurality of crushing drills 23 fixedly mounted on the outer wall of the driving rod 22 on the side close to the drill bit 21, and a crushing motor 24 fixedly mounted on the top of the driving rod 22; A plurality of sampling grooves 311 are provided on the outer wall of the sampling cylinder 31, and a rotating groove 3111 is provided inside the sampling groove 311. The rotating groove 3111 is in a circular ring shape. A circular ring plate 312 is fixedly provided on the top of the sampling cylinder 31, and a through groove 321 is provided on the outer wall of the sealing sleeve 32. The through groove 321 matches the size of the sampling groove 311.

[0024] The above scheme is adopted: by using the cooperation of the universal wheel 11 and the push handle 12 to move the entire mobile base 1 to the place where sampling is required, the ore to be sampled can be crushed by using the crushing mechanism 2 after the movement, and the driving rod 22 is driven to rotate by the crushing motor 24, thereby driving the drill bit 21 at the bottom and multiple crushing drills 23 to rotate synchronously to achieve a rapid crushing effect. The crushed ore is more convenient for sampling. After the crushing is completed, the electric cylinder 34 is used to control multiple or single sampling tubes 31 to move downward for sampling. During the sampling process, the adjustment block 33 and the electric push rod 331 can be used to achieve the desired effect. For sampling of ores at different heights, the driving component 35 is used to adjust the position relationship between the sealing sleeve 32 and the sampling tube 31, so that the sealing sleeve 32 rotates along the rotating groove 3111 to open and close the sampling groove 311. When sampling is required, the through groove 321 is overlapped with the sampling groove 311 to facilitate the entry of the ore sample into the sampling tube 31. When sampling is completed, the through groove 321 is moved away from the sampling groove 311, and the sampling groove 311 is closed to avoid overflow of the sample during the upward rotation process. At the same time, the adjustment component 37 is used to adjust the positions of multiple sampling tubes 31 to achieve the effect of zoned sampling.

[0025] like Figure 5 As shown, the driving assembly 35 is used to drive the sealing sleeve 32 to rotate in the rotating groove 3111 to achieve the regulation of the state of the sampling groove 311; The driving assembly 35 includes a plurality of first gears 351 distributed in a circular array, a second gear 352 located at the center of the first gear 351 and a protective sleeve 353 sleeved on the outside of the crushing motor 24 , and the plurality of first gears 351 are all engaged with the second gear 352 .

[0026] The above scheme is adopted: through the coordinated linkage of the drive component 35 and the crushing mechanism 2, a reasonable sampling effect is achieved. Specifically, the crushing motor 24 is used to rotate the drive rod 22, thereby causing the second gear 352 on the drive rod 22 to rotate synchronously. Since the second gear 352 is engaged with the first gear 351, it will drive multiple first gears 351 to rotate synchronously during the rotation process, thereby causing the multiple electric cylinders 34 and the sealing sleeve 32 at the bottom to rotate synchronously, causing the sealing sleeve 32 to rotate inside the rotating groove 3111, thereby achieving the adjustment of the opening and closing state of the sampling groove 311, which is convenient for sampling and transportation of samples.

[0027] like Figure 6 As shown, the disassembly assembly 36 is used to quickly disassemble and separate the sampling tube 31 and the sealing sleeve 32; The disassembly and assembly component 36 includes two plug plates 361 fixedly arranged on both sides of the top of the circular plate 312, two arc grooves 362 opened on the top of the sealing sleeve 32, and a limit plate 363 rotatably arranged on the top of the plug plate 361. The plug plate 361 and the limit plate 363 are the same size and shape and both are slidably inserted in the arc groove 362, and the limit plate 363 abuts against the top of the arc groove 362.

[0028] The above solution is adopted: the sampling tube 31 and the sealing sleeve 32 can be quickly disassembled and assembled by disassembling the assembly 36, so that the sampling tube 31 can be removed from the sealing sleeve 32 for replacement and cleaning, thereby avoiding affecting the sampling and detection results in the later stage. Specifically, when disassembly is required, the limit plate 363 can be manually rotated to drive the limit plate 363 to coincide with the position of the bottom plug-in plate 361. At this time, the plug-in plate 361 and the limit plate 363 can be easily moved from the arc groove 362, thereby driving the entire sampling tube 31 to move out from the bottom, so that the sampling tube 31 can be removed from the bottom. 1 is separated from the sealing sleeve 32. After cleaning and replacement, it is inserted into the outer wall of the sealing sleeve 32 along the rotating groove 3111, so that the limiting plate 363 passes through the arc groove 362. At this time, the limiting plate 363 is rotated to a vertical position with the inserting plate 361, thereby achieving the effect of installation and fixing, and preventing the sampling tube 31 from falling off from the sealing sleeve 32. The inserting plate 361 and the limiting plate 363 are both made of rubber eraser material, which has great elasticity and sealing performance. When it is clamped inside the inserting plate 361, it will not fall off with its rotation.

[0029] like Figure 9As shown, the adjustment assembly 37 includes a rotating frame 371 rotatably set on the driving rod 22, a rotating disk 372 fixedly set on the top of the protective sleeve 353, a driving disk 373 rotatably engaged with the inside of the rotating disk 372, a connecting column 374 fixedly set at the center of the top of the driving disk 373, a protrusion 375 fixedly installed on one side of the connecting column 374, a rotating rod 376 fixedly set at the center of the top of the connecting column 374 and rotatably connected to the top of the movable seat 1, and a rotating adjustment motor 377 fixedly set at the top of the movable seat 1 for driving the rotating rod 376 to rotate. The rotating frame 371 is cross-shaped and the bottom of one end away from the center is rotatably connected to multiple first gears 351. The protective sleeve 353 is fixedly connected to the top of the rotating frame 371. The crushing motor 24 is fixedly connected to the top center of the rotating frame 371. Protruding rods 3711 are fixedly provided at the four corners of the top of the rotating frame 371. The top of the rotating disk 372 is provided with a plurality of circular grooves 3721 distributed in an annular array, and the plurality of circular grooves 3721 form a flower shape. The cross-section of the driving disk 373 is in the shape of an "I" character and is clamped inside the circular groove 3721 to prevent the rotating disk 372 from falling. The protrusion 375 contacts the protruding rod 3711 and drives the protruding rod 3711 to rotate. The crushing mechanism 2 and the partition sampling mechanism 3 are both located at the top of the slot 13, and a collection box 4 is placed on one side of the top of the movable base 1.

[0030] The above scheme is adopted: the adjustment component 37 is used to adjust the positions of the multiple sampling cylinders 31, so that the multiple sampling cylinders 31 can be sampled in different areas. Specifically, the adjustment motor 377 can be used to drive the rotating rod 376 to rotate, thereby causing the protrusion 375 and the driving disk 373 to rotate synchronously. During the rotation, the protrusion 375 on the connecting column 374 will be driven to rotate, so that the protrusion 375 hits the protruding rod 3711, thereby driving the rotating frame 371 to rotate synchronously, so that the driving disk 373 moves from the rotating disk 372 on the rotating disk 372 to the next rotating disk 372, thereby achieving the effect of intermittent rotation, thereby driving the multiple protective sleeves 353 at the bottom to rotate intermittently, and achieving the position adjustment of the multiple sampling cylinders 31 at the bottom. The adjustment of the position makes it rotate to the side away from the push handle 12 in turn for sampling in batches. During the sampling process, the electric push rod 331 can be used to drive the adjustment block 33 to adjust the height in the sampling tube 31, thereby achieving sampling of ores at different heights. After sampling, the driving component 35 drives the multiple sampling slots 311 to be sealed, and then the adjustment component 37 is used to rotate the sampling tube 31 after sampling to move it to the collection box 4. The unsampled sampling tube 31 moves to the top of the slot 13, and then the sampling slot 311 is opened to allow the sample in the sampling tube 31 at the top of the collection box 4 to fall into the collection box 4 for collection, which also facilitates the downward movement of the sampling tube 31 at the top of the slot 13 for sampling.

[0031] The working principle and use process of the present invention are as follows: when using the device, the universal wheel 11 and the movable base 1 can be moved to the sampling location by manually pushing the push handle 12, and the crushing motor 24 can be used to drive the drill bit 21 and the crushing drill 23 to rotate to crush the ore to be sampled. After crushing, the sampling barrel 31 at the top of the slot 13 is moved down by the electric cylinder 34, and at the same time, the engagement of the first gear 351 and the second gear 352 drives the sealing sleeve 32 to rotate in the rotating groove 3111, opening the sampling slot 311 to facilitate its descent for sampling. After the sampling is completed, the sampling slot 311 is closed by rotating the sealing sleeve 32, and the sampling barrel 31 at the top of the slot 13 is driven upward by the electric cylinder 34. After moving upward, it is driven by the adjusting component 37 Multiple sampling barrels 31 rotate intermittently, and the sampled sampling barrels 31 are moved to the top of the collection box 4, and the unsampled sampling barrels 31 are moved to the top of the slot 13. By opening the sampling slot 311 here, the sample in the sampling barrel 31 at the top of the collection box 4 is discharged, and the sampling barrel 31 at the top of the slot 13 is driven downward by the electric cylinder 34 at its top to sample here. When sampling, the electric push rod 331 can be used to drive the adjustment block 33 to move in the sampling barrel 31 to adjust the internal regional cavity of the sampling barrel 31 to achieve sampling of ores at different heights. At the same time, during the intermittent rotation, the movable seat 1 can be moved to enable multiple sampling barrels 31 to sample ores at different positions, thereby achieving partitioned sampling and improving the sampling efficiency of the ore.
